Examination should include
- comparing and contrasting analog and digital signals
- defining the voltage levels for digital logic circuits
- describing the operation of OR, AND, inverter, NAND, NOR, XOR and XNOR logic gates
- recognizing the schematic symbol for each basic logic gate
- constructing truth tables for each of the basic logic gates
- assembling circuits with the basic logic gates and verifying their operation using truth tables
- troubleshooting logic circuits with a logic probe.
Process/Skill Questions:
- Why is it important to know the truth table of each basic logic gate?
- What is the difference between an analog and a digital signal?
- What is the advantage of using a logic probe over a digital multimeter when troubleshooting basic logic circuits?
